Step 2: Contact a doctor if symptoms persist

Seek medical advice when an atrial fibrillation episode does not subside

Most atrial fibrillation episodes are not immediately life-threatening, but it is very difficult to assess the severity of this condition at home. If symptoms persist for many hours without improvement, you should contact your doctor for guidance and timely evaluation.

• Do not be complacent when an abnormal heart rhythm persists.
• Monitor the onset and progression of symptoms.
• Note any accompanying signs such as palpitations, shortness of breath, dizziness, or fatigue.
• Proactively seek medical advice instead of waiting for symptoms to disappear on their own.

Report any measures already taken at home

When talking to your doctor, providing complete information will help make the evaluation and treatment process more effective.

• State any relaxation or self-care measures you have taken.
• Report if you have rested, stayed hydrated, or used breathing techniques.
• Describe the extent of symptom improvement or lack thereof.
• Provide the duration of the atrial fibrillation episode as accurately as possible.

Inform your doctor about medication use

Information about current medications plays an important role in identifying the cause and choosing appropriate treatment methods.

• Tell your doctor all the medications you are currently taking.
• Report if you have taken your atrial fibrillation medication as prescribed.
• Specify if you missed a dose or arbitrarily changed the dosage.
• Update any supplements or over-the-counter medications you are using.

Additional medical treatment may be necessary

In some cases, self-care measures at home are not enough to control atrial fibrillation episodes. The doctor may consider appropriate treatment options based on the specific condition of each patient.

• Adjusting or supplementing medication.
• Monitoring heart rate and cardiovascular indicators.
• Assessing the risk of complications related to arrhythmia.
• Proposing more intensive treatment methods if necessary.

If atrial fibrillation episodes last for several hours, recur frequently, or are accompanied by chest pain, shortness of breath, fainting, or impaired consciousness, seek medical attention immediately for timely examination and treatment.

Step 3: Electrical cardioversion for atrial fibrillation

Discuss electrical cardioversion with your doctor

When atrial fibrillation episodes are prolonged or do not respond well to conventional treatments, the doctor may consider performing electrical cardioversion. This is a medical procedure that helps restore a normal heart rhythm by using a controlled and precisely calculated electrical current.

• Often indicated in some cases of prolonged atrial fibrillation or when it causes significant symptoms.
• Performed in a medical facility under the supervision of a specialized team.
• The goal is to bring the heart rate back to a stable and more regular state.
• The decision to perform it will depend on the individual patient's health condition.

How does the procedure work?

Electrical cardioversion is a relatively quick procedure performed in a strictly controlled environment.

• The patient will be given short-acting anesthesia or sedation before the procedure.
• The doctor places electrodes on the chest to deliver an electrical impulse to the heart.
• A short electrical shock will be used to restore the heart's normal electrical activity.
• After the procedure, the heart rate will be monitored to assess the effectiveness of the treatment.

Patients usually feel no pain

Many people are apprehensive when they hear about electrical cardioversion. However, during the procedure, patients usually do not feel any pain because they are properly anesthetized or sedated.

• The procedure usually lasts for a short time.
• The patient is not conscious when the electrical shock is delivered.
• Any discomfort after the procedure is usually mild, if present.
• Most patients can recover quickly after stable monitoring.

Not everyone is suitable for electrical cardioversion

Although this method is effective in many cases of atrial fibrillation, the doctor will carefully consider before recommending it.

• Overall health status can influence treatment decisions.
• Some people may need medication before or after the procedure.
• The risk of blood clot formation needs to be carefully assessed.
• The doctor will choose the most suitable treatment option based on the patient's medical history and the severity of the arrhythmia.

Electrical cardioversion is an effective treatment method that helps restore a normal heart rhythm in many people with atrial fibrillation episodes. If your doctor suggests this procedure, discuss the benefits, risks, and preparatory steps thoroughly to make an informed decision for your health condition.

Step 4: Use medication correctly to control atrial fibrillation

Adhere to medication as prescribed by your doctor

Medication is an important part of treating atrial fibrillation and preventing recurrent atrial fibrillation episodes. Using medication at the correct dosage, time, and as directed can help control heart rate, reduce symptoms, and limit the risk of complications.

• Take medication exactly as prescribed.
• Do not stop medication on your own when symptoms improve.
• Do not increase or decrease the dosage on your own.
• Maintain follow-up appointments as scheduled for the doctor to evaluate treatment effectiveness.

Antiarrhythmic drugs help maintain a stable heart rhythm

Your doctor may prescribe antiarrhythmic drugs to help your heart maintain a stable rhythm and reduce the risk of arrhythmia episodes.

• Some drugs work to restore or maintain a normal heart rhythm.
• The choice of medication depends on age, underlying medical conditions, and the severity of atrial fibrillation.
• If the current medication does not provide the desired effect, the doctor may consider adjusting the treatment regimen.
• Do not change medication without your doctor's approval.

Additional heart rate control medication may be prescribed

In addition to antiarrhythmic drugs, some patients need to take additional medication to help control their heart rate.

• Helps reduce rapid heart rate or palpitations.
• Helps the heart function more efficiently during treatment.
• Can be used alone or in combination with other drug classes.
• Adhere to usage instructions to achieve optimal effectiveness.

Anticoagulant drugs help reduce the risk of stroke

People with atrial fibrillation have a higher risk of blood clot formation than normal. If a blood clot travels to the brain, the risk of stroke can significantly increase.

• Your doctor may prescribe anticoagulant drugs to reduce this risk.
• Take medication at the correct dosage and time as directed.
• Do not stop medication on your own as it may increase the risk of complications.
• Report any unusual bleeding to your doctor.

Monitor for side effects of medication

Like many other medications, drugs for atrial fibrillation can cause some unwanted side effects in some people.

• Nausea.
• Dizziness.
• Fatigue.
• Feeling sluggish or having low energy.

If these symptoms persist, become severe, or affect daily activities, contact your doctor for advice and treatment adjustment when necessary.

Adherence to treatment plays a crucial role in controlling atrial fibrillation episodes, maintaining a stable heart rhythm, and reducing the risk of serious complications such as heart failure or stroke.

Duration of atrial fibrillation episodes

Atrial fibrillation episodes can vary in duration for each person

Not all atrial fibrillation episodes are the same. The onset and severity of symptoms can vary significantly depending on the individual's health status, the underlying cause, and their response to treatment.

• Some episodes only last for a few hours and then resolve on their own.
• Some cases can last for several days.
• Some people experience atrial fibrillation episodes that last for weeks if not effectively controlled.
• Symptoms may appear and disappear multiple times in phases.

Types of atrial fibrillation are classified by duration of onset

Doctors often rely on the duration of symptoms to assess the condition and choose appropriate treatment methods.

• Paroxysmal atrial fibrillation: Episodes appear suddenly and resolve on their own within a few hours or days.
• Persistent atrial fibrillation: The condition lasts longer and usually requires medical intervention to restore a normal heart rhythm.
• Long-standing persistent atrial fibrillation: Symptoms persist for a long time, often for many months.
• Permanent atrial fibrillation: The irregular heart rhythm is continuous, and there is no longer a goal of restoring a normal sinus rhythm.

Some people may have continuous atrial fibrillation

In some patients, arrhythmia does not only occur in episodes but is almost continuous.

• May not notice obvious symptoms even if the irregular heart rhythm persists.
• Some people often feel palpitations, fatigue, or reduced ability to exercise.
• The risk of complications such as stroke or heart failure can increase if not monitored and treated appropriately.
• Regular follow-up appointments help accurately assess the progression of the disease.

Monitoring the duration of symptom onset is very important

Recording the start time, duration, and accompanying symptoms can help your doctor more accurately assess the severity of atrial fibrillation episodes.

• Keep a record of episodes of rapid heart rate or palpitations.
• Monitor factors that may trigger symptoms.
• Inform your doctor if episodes occur more frequently or last longer than before.
• Do not be complacent if symptoms last for many hours or several consecutive days.

Understanding the duration of atrial fibrillation episodes helps patients proactively monitor their health, recognize abnormal signs, and effectively cooperate with their doctor in the treatment process.
